Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] As shown in Figure 1 and 2.

[0041] A method for tracking a moving target with a mobile antenna, the steps of which are:

[0042] a. Set up a multi-point receiving small antenna system on the mobile platform. These small antennas choose to receive 3 and 4 global navigation and positioning satellite signals and data at the same time, and send them to the mobile platform multi-point receiving and processing system. The mobile platform multi-point reception and The processing system gives the position of the mobile platform and the attitude angle relative to the local horizontal coordinate system, that is, the data of heading angle, pitch angle and roll angle;

[0043] b. Set up a multi-point receiving small antenna system on the mobile antenna. These small antennas choose to receive 3 and 4 global navigation and positioning satellite signals and da...

Abstract

The invention discloses method and system of mobile type antenna of gyroscope with no inertia for tracking moving object based on satellite navigation positioning in order to solve issues of slow drift of data, and poor precision existed in current tracking antenna of gyroscope with inertia. The system includes mobile platform and antenna system, small antenna system of mobile platform for multipoint reception, small antenna system of mobile antenna for multipoint reception, multipoint reception / process / transform system of mobile platform, multipoint reception / process / transform system of mobile antenna, system for calculating target bearing angle and pitch angle, transforming and multiplying equipment, and device for driving wave packet of antenna etc. Rational design makes the system possess features of multifunction, superior performance, flexible use, and propagable stepped across different applications.

Description

technical field [0001] The invention relates to a wireless tracking technology, in particular to a method and a system for tracking a moving target with a mobile antenna. Background technique [0002] The mobile antenna tracking control system is to enable the mobile antenna to track the movement in order to realize the communication transmission between the mobile antenna and the moving target (such as vehicles, ships, aircraft or outer space targets, etc.), TV transceiver, remote control telemetry and tracking measurement. Target automatic control system. The traditional mobile antenna tracking control system consists of a mobile platform (such as land-based vehicles, sea-based, space-based and space-based platforms), a mobile antenna installed on the mobile platform, and a land-based or mobile system that determines the position of the mobile platform and the mobile antenna. The navigation and positioning system on the platform, the electromechanical inertial gyroscope t...
